If the Data Set is evaluated as a tree structure, this method returns the first item on the same level as element with the same parent as element, that has Tag tag.
Please note that the numbering of the items of interest in this first illustration is arbitrary and does not imply order.
If the passed object points to: | The method returns an object pointing to: |
---|---|
Item 1 | The first sibling (same level, same parent) of Item 1 that has Tag tag, if such an item exists. If such an item does not exist, the method returns null. |
Item 2 | The first sibling (same level, same parent) of Item 2 that has Tag tag, if such an item exists. If such an item does not exist, the method returns null. |
Item 3 | The first sibling (same level, same parent) of Item 3 that has Tag tag, if such an item exists. If such an item does not exist, the method returns null. |
If the Data Set is evaluated as a list, this method returns the first item in the entire list that has Tag tag. The search begins at the top of the list.
Please note that the numbering of the items in the following illustration does indicate the order of the items when the Data Set is evaluated as a list.
If the passed object points to: | The method returns an object pointing to: |
---|---|
Item 1 | The first item in the list that has Tag tag, if such an item exists. Searching begins at the top of the list. If an item with Tag tag is not found, null is returned. |
Item 14 | The first item in the list that has Tag tag, if such an item exists. Searching begins at the top of the list. If an item with Tag tag is not found, null is returned. |
Item 22 | The first item in the list that has Tag tag, if such an item exists. Searching begins at the top of the list. If an item with Tag tag is not found, null is returned. |
